Abstract (en)

[origin: EP3168550A1] Provided is a liquid supply system with an improved pumping function. The liquid supply system includes first and second bellows 41 and 42 arranged in series in an expanding/contracting direction thereof in a vessel 12 and having first end portions respectively, which are close to each other and fixed to an inner wall of the vessel 12, and also having second end portions respectively, which are distant from each other and movable in the expanding/contracting direction. An inner space of the vessel 12 located outside the first bellows 41 serves as a first pump chamber P1. An inner space of the vessel 12 located outside the second bellows 42 serves as a second pump chamber P2. An inner space of the vessel 12 located inside the first and second bellows 41 and 42 serves as a sealed space R1. A shaft 15 to which the respective second end portions of the first and second bellows 41 and 42 are fixed is reciprocally moved to expand/contract the first and second bellows 41 and 42.
